Assume that the readings at freezing on a batch of thermometers are normally distributed with a mean of 0◦C and a standard deviation of 1◦C. A single thermometer is randomly selected and tested. Find P48, the 48-percentile. This is the temperature reading separating the bottom 48% from the top 52%.

    Step-by-step explanation:

    Given that the readings at freezing on a batch of thermometers are normally distributed with a mean of 0◦C and a standard deviation of 1◦C.

    When a single thermometer is randomly selected we have the temperature is

    N (0,1)

    To find 48th percentile

    If 48th percentile is c

    then f (x
    c = 0.05

    Hence we have P48 is 0.05
